ULYSSIS A. SHIREY, OF KANSAS CITY, MISSOURI.

Specification of Letters Patent.

Patented J une 9, 1914.

Application led March 28, 1912. Serial No. 686,830.

To all whom it may concern Be it known that I, ULYssIs A. Similar, a citizen of the United States, residing at Kansas City, in the county of Jackson, 'State of Missouri, have invented certain new and useful Improvements in Corn-Harvesters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new` and useful improvements in corn harvesters.

An object of this invention is the provision of a corn husker which will cut the standing corn and convey the same into the path of the operating mechanism.

A still further object of this invention is to improve and simplify devices of this character, rendering them comparatively simple and inexpensive to manufacture, reliable and eliicient in use and readily operated.

lVith the above and other objects in View, this invention resides in the novel features of construction, formations, combinations and arrangements of parts to be hereinafter more fully described and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of my improved husker. Fig. 2 is a top plan View thereof. Fig. 3 is a horizontal sectional View taken on the line 3-3 of Fig. 1. Fig. 4 is a horizontal sectional view taken on the line 4-4 of Fig. 1. Fig. 5 is a rear elevation with portions removed. Fig.` 6 is a cross sectional view taken on the line G-6 of Fig 1 with the rear wheeled axle in elevation. Fig. 7 is a cross sectional view taken on the line 7-7 of Fig.` 1, and Fig. 8 is a cross sectional View taken on the line 8-8 of Fig. 1.

Referring to the accompanying drawings b-y similar characters of reference throughout the several views, the numeral 10 designates generally my improved husker which comprises a frame 11 consisting of upper and lower longitudinal bars 12 and 13 connected at their ends by upper and lower cross bars 14 and 15 and at intervals throughout their length by vertical bars 16.` A suitable platform or engine bed 17 is supported by the intermediate bars 16 adjacent their upper terminals and supports an engine 18. The forward terminals of the bars 13 are prolonged as shown at 19 and are connected at their free extremities by a transverse bar 20.

A pair of spaced shoes 21 are secured to the bar 20 extending forwardly therefrom and have slidable therein a cutter bar 22 which has secured to its upper side a plurality of blades 23 which copcrate with the guard fingers 24 and serve to cut the stalks of corn engaged thereby. The cutter bar 22 has pivotally secured to one end a link 25 connected to the wrist pin 2G which extends eccentrically from the disk 27 keyed to the forward terminal of a countershaft 2S journa led in suitable bearings 29 attached to one of the bars 13 and the prolongation thereo 19. Y

The frame 11 has journaled at its rear end an axle 30 carrying keyed at its opposite terminals rear traction wheels 31. This axle 30 has securely keyed thereon a beveled pinion 32 which meshes with a similar pinion 33 keyed to thc shaft 34 which is connected to the shaft 28 by means of a knuckle joint 35 andserves to cause the operation of the cutter bar 22 upon the rotation of the axle 30. The front axles 3G are secured beneath the forward endof the frame 11 and carry the front supporting wheels 37. A pair of vertical bars 3S are secured to the ends of the axles 36 and extend for vertical movement through the guides 39 secured to the bars 12 and 13.` The upper ends of the rods 38 are connected by a bar 40 which is provided intcrmediate its ends with a pair of spaced ears 41 between which is pivoted a lifting lever 42 fulcrumed at one end as at 43 to a vertically extending bracket 44 secured to the front bar 14. A pawl 45 is mounted upon the free end of the lever 42 and is operated so as to be thrown into and out of engagement with a segmental rack bar 46 by a hand lever 47. The bracket 44 and the rack bar 46 are connected to the frame 11 by suitable braces 48. Obviously when the lever 42 is raised or lowered by the person who may sit in the operators scat 48, the forward end of the frame 11 will be raised or lowered with respect to the wheels 37. The rods 38 have extending forwardly therefrom crank arms 49 which are connected by crossed links 50 to a pair of crank arms 51 which extend laterally from the steering standard 52 which is equipped with a hand wheel 53 upon the rotation of which journaled within the frame 11 adjacent the bottom thereof and are 'connected by a suitable conveyer 56 which carries the stalks of. corn deposited thereon to a pair of super-V posed rollers 57 and 58 keyed upon the shafts 59 and 60 journaled upon the rear bars 16. The shafts 59 and 60v are rotated in opposite directions by a chain drive 61 from the shaft 55 and a chain drive 141 from shaft 66.

As theL stalks of corn are moved reari wardly of the frame11 uponA the upper lap .f of the conveyer 56, the same will be positively driven between the rollers 57 Vand 58 by a conveyer 62 supported byV a pair of; rollers 63 and 64 keyed to the shafts 65 and i 66 ournaled upon the intermediate uprights 16. A battle plate 67 whichris preferably curved in cross section causes the stalks to be moved beneath the conveyer 62 endwise i with respect to the longitudinal axis of the 1 said conveyer. beneath the roller 57 the ears will be stripped As the corn-stalks are forced r `therefrom 'and be dropped into the lowerI end of the transverse conveyer casing 68 in which is located a conveyer 69 supported by a pair of rollers 70 and 71. The said casing 68 extends transversely of the frame 11 and i is then extended upwardly as at73 tcrminating in a discharge chute74 for .a purpose to be later disclosed.V In orderto provide for the turningof the conveyer inthe elbow j of the casing the flights y75 terminate at the ends short of the side edges of the conveyer belt 76, the marginal edges of which are engaged by rollers 7 7 which hold the conveyer from contact with the conveyer casing.

The shaft 78 which supports thedriven roller 7 O of the conveyer is equipped with a sprocket wheel 79 connected by a chainv80 to a sprocket 81 keyed to the adjacent terminal of the countershaft`82, the said shaft being j ournaled in suitable bearings 83 supported by one of the bars 13 and provided at its opposite end with. a pinion 84 engaging the above mentioned gear V32 secured to one of the drive wheels 31 thus providing a means for operating the conveyer. A pair of guide plates 86 are secured to the front end of the frame 11 in any suitable manner and are converged inwardly at their intermediate points as indicated by the numeral 87. A pair of shafts 88 rand 89 are journaled upon the ends of the plates 86 and have keyed thereon sprocket wheels 90 over which pass conveyer chains 91 formedwith teeth 92 and when the inner laps of the chains which ride upon the inner faces of the plates are propelled rearwardly, and during advance of the machine the said teeth will engage the corn stalks which have been severed adjacent the ground by the cutting blades 23 drawing the same inwardly forengagement with the baille plate 67 .causing them to be disposed lengthwise'upon the conveyor 56. n

The upper vextremities of the shafts 89 have keyed thereon beveled pinions 93 which mesh with similar pinions 94-keyed to a transversely extending shaft 95 journaled in suitable bearings 96 attached to the upper edge of one lo-f the bars 14. The shaft 95 has securely keyed thereona beveled pinion 97 which meshes with a beveled pinion 98 l carried by the upper terminal `ofa vertical counter shaft 99 supported in vbearings 100 Vsecured at convenient points upon the frame 11. The lower terminal of the shaft 99 is provided with a beveled pinion 101- which meshes with a similar pinion 192 carried `'by the shaft 28 thus providing a means for operatingathe chains91 uponthe rotation of the said shaft 28.

A husking frame 119 is secured to the -upsoY rights 16 below the mouth of the chute 74 and comprises a pair of side plates 120 connected at their terminals by end plates 121 which latter have journaled ltherein a-plurality of'huskingrollers 122 formed with radially projecting fingers 123. The shafts are rotatably connected by a chain of gear wheels 124 which are driven by a gear wheel 125 keyed to a shaft 126 to the louter end of which is fixed a sprocket wheel 127 connected by a sprocket chain 128 to a sprocket l wheel 129 keyed to the drive shaft 139 to the enginev 18. A seco-ndsprocket wheel 131 is also keyed to thedrive `shaft and is connected by a sprocket chainv 132 to La sprocket wheel 133 carried .by a transverse shaft 134 journaled upon the intermediate uprights 16. This shaft 134 has keyed thereon adjacent t-he sprocket Wheel 133,'and at its terminal a pair of sprocket'wheels 135 and 136, over the former of which passes a chain to a sprocket wheel 137 carried by the shaft 65 by which provision is made to im-v part motion to the conveyer 62, while the chain 138 passes over the sprocket wheel 1136 and overa wheel 139 carried by the rear axle 30 .and serves to provide for the driving of the traction wheel 31 and various operating elements connected to the said shaft 30. The shaft 66 is provided with a sprocket wheel 140 over which passes a.

chain 141 for engagement with a sprocket wheel Y142 serving to vcause the rotation 'of the roller 57. The shaft 126 isprovided with a pulley 142 for enga-gementl with a belt .143, which through-.the medium of ka pulley 144 serves to impart a rotary movement to the shaft 145 and -drive Vthe con-` Vthe rollers57 and 58 upon a dumpingframe` aoc lier

147 operated by a lever 148 fulcrumed upon the frame 11 as at 149 and which is connected to the arm 150 of the `dumping frame by a link 151. The lever 148 is locked against movement by the engagement of its pawl 152 with a segment 153 supported also by the frame 11. The rear end of the conveyer belt 146 passes overaroller 154 carried by a shaft 155 which inturn is connected to the shaft by a sprocket `chain 156 which passes over sprocket wheels 157 and 158 carried by the shafts 155 and 55 respectively.

As clearly illustrated in Fig. 6 of the drawings, the rollers 122 slant toward one side of the frame 11 at which point is located the mouth 15S of a vertical chute 159 which is secured to the said frame 11. This chute comprises a casing which is substantially rectangular in cross section and which has extending from its lower end an inclined casing 160 provided with a depending spout 161 beneath which is. preferably located a wagon or other suitable container (not shown in the drawings). A `pair of shafts 162 and 163 are journaled in the opposite ends of the extension 160 to support rollers 164 and 165 over which passes a conveyor belt 166 by means of which the husked ears will be deposited into the said container (not shown in; the drawings). The shaft 162 has keyed thereon a sprocket wheel 167 which engages a sprocket chain 168 connected at its opposite end to a sprocket wheel 169 carried by the shaft 34.

The operation of the machine is as follows: The forward end of the frame is first adjusted with respect to the front supporting wheels 37 to its proper height in order that the blades 23 will sever the stalks at a proper distance from the ground. Power is then applied to the rear axle 30 and the machine is propelled over the ground by the `traction wheels 31, being guided by the steering mast 52. As the guard lingers 24 engage the corn stalks the latter will be thrown between the blades 23 and` upon the oscillation of the cutter bar 22 will be severed and deposited lengthwise upon the upper lap of the conveyer 56 by toothed chains 91 and baille plate 67. As the upper lap of the conveyer 56 moves rearwardly the stalks will be forced lengthwise between the rollers 57 and 58 by the conveyer 62. The ears of corn will be obviously stripped therefrom and permitted to drop into the casing 72 from whence they will be conveyed upwardly through the extension 73 and deposited through the chute 74 upon the husking rollers 122. The stripped stalks will pass through the rollers 57 and 58 and be deposited upon the dumping frame 147. Upon the rotation ofthe husking rollers 122 the radial fingers 123 will strip the husks from the ears causing the same to be dropped through the rollers upon the conveyor 146 from whence they will be deposited upon the dumping frame 147. The husked ears will then pass downwardly through the chute 159 for the engagement with the con- Veyer 166 which will transfer them to the container (not shown) through the spout 161.

From the foregoing disclosures taken in connection with the accompanying drawings, it will be manifest that a machine for cutting corn and removing the husks therefrom is provided which will fulfil al1 of the necessary requirements of such a device.

Having thus fully described this invention what I claim as new and desire to protect by Letters Patent, is

In a corn husker, a main frame, a cutter bar, a horizontal endless carrier in rear of said cutter bar having the upper lap moving rearwardly in said frame, a pair of vertically disposed endless carriers above said cutter bar and horizontal carrier and serving to carry stalks rearwardly in upright position upon said horizontal carrier, and an inclined baffle plate having an arched top adapted to knock down the upright stalks into lengthwise position during passage of the stalks therethrough upon said horizontal carrier.

In testimony whereof, I ailix my signature, in presence of two witnesses.
